GEORGE KRAMER, .O-F DYSART, IOWA.

WEED-DESTROYER.

To all whom it may concern:

Be it known that I, GEORGE KRAMER, citi-' zen of Transylvania, formerly Austria-Hungary, residin at Dysart, in the county of Tama and tate of lowa, have invented certain new and useful Improvements in Weed-Destroyers; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention to produce a compound which may be strewed over fields composition of materials,

portions stated, and by Weight: lye, 10 parts,

slack coal, 4O parts,.sa'ltpeter,' 20 parts, salt,

' 10 parts.

' out of'the soil;

These are mixed in any order, and when intimately commingled form a powdery mass, practically dry,-which maybe sown by hand, or otherwise, over a weed-infested field. In a day or twothe weeds will have-.

been killed, even to the roots; The field may then be plowed, preferably after. a few weeks allowed for some of the poison to pass Experience hasshown that Specification of Letters Patent.

such as. Canada in about the pro-- of saltpeter.

In testimony. whereof I afiix mysi'gnature a good crop, of oats or corn, may be grown from soil so treated. A better practice, however, is to turn a drove of hogs into the field, and allow them to root it over, which they a do most thoroughly, consuming the dead roots of the weeds with relish. This is in part due to the presence of salt. and in part to their liking for slack coal, which is used for this purpose,'and also to give body to the mixture. When well rooted over the field is plowed. and tilled in the usual way,

and will be found to be weed-free and productive.

' By slackcoal is to be understood the finely granulated residual coal deposited in the handling ofcoal, or screened fromv the coarser elements thereof, the term being in general commercial use.

Having thus described my invention, I claim:; v I

A weed-destroying compound, composed of substantially equal portions of lye and salt, 'a-larger portion than either of saltpeter, and a larger portion of slack coal than in presence of' two Witnesses.
